Frequently Asked Questions (FAQs)

1. What is the difference between socket head screws and socket head cap screws?

Socket head screws and socket head cap screws have different applications. Socket head cap screws are used in high-strength and high-torque applications, often joining heavy-duty components. On the other hand, socket head screws are suitable for tight spaces or areas with difficult access, providing a flush finish and allowing for easy tightening and loosening of bolts.

2. Why use a socket head cap screw?

Socket head cap screws are convenient to use as they can be easily tightened or loosened without requiring external clearance like hex head screws. This makes them ideal for tight areas where other fasteners may not fit properly.

3. What are the different types of socket head cap screws?

There are three main types of socket head cap screws: socket cap screws, flat socket cap screws, and button socket cap screws. These screws come in standard diameters ranging from 00-90 through 1/2 (0.500) and are available in various standard and specialty materials.

4. What is the difference between socket head and Phillips head?

Socket head screws have a hexagonal socket for turning with a wrench, while Phillips head screws have a low-profile, countersunk head. Socket head screws are ideal for applications that require a flush mount and a strong fastener, while Phillips head screws are commonly used for different purposes.

5. Are socket head screws stronger?

Socket head screws are known for their strength. In fact, standard inch series socket head screws are 20% stronger than Grade 8 hex head screws and 50% stronger than Grade 5 hex screws. They have a minimum tensile strength of 180,000 psi for sizes up to 1/2' diameter and 170,000 psi for sizes 5/8' diameter and above.

6. How strong are socket head cap screws?

Socket head cap screws made of standard alloy steel have strength levels of 180,000 and 170,000 psi, meeting industry standards. However, particular brands like UNBRAKO maintain socket cap screws with even higher strength levels, consistently at 190,000 and 180,000 psi depending on the screw diameter.
